// Homework 18, challenge: Sum 1..N.
//
// Prompt for a positive whole number n. Compute 1 + 2 + ... + n with a
// for loop and a running total. Print:
//   Sum from 1 to N is S
// Then print the result of n * (n + 1) / 2 on the next line to confirm
// the two match.
//
// You need more packages. Change the import line to:
//   import (
//       "bufio"
//       "fmt"
//       "os"
//       "strconv"
//       "strings"
//   )
//
// Run with: go run exercises/18/homework/04-sum-1-to-n.go
